Nano-selenium protein nutrient solution for animals and plants and preparation method of nano-selenium protein nutrient solution

Abstract

The invention discloses a nano-selenium protein nutrient solution for animals and plants and a preparation method of the nano-selenium protein nutrient solution for animals and plants, and the nano-selenium protein nutrient solution for animals and plants is prepared from, by weight, 7g of glycine, 7g of glutamic acid, 9g of cysteine, 380g of methionine, 23g of yeast, 15g of glucose, 12g of sodium selenite, 10g of phenylalanine and 5kg of water. The invention also provides a preparation method of the nano-selenium protein nutrient solution for animals and plants. The method comprising the following steps: S1, material preparation / screening: selecting required materials, screening through a screen, controlling the particle size of the materials, removing impurities in the materials, and improving the product purity. The preparation method can well change the preparation method of a traditional nano-selenium protein nutrient solution, improves the preparation efficiency of the nano-selenium protein nutrient solution, is convenient for animals and plants to use, can effectively promote the growth and development of the animals and plants, can well improve the storage capacity of the animals and plants, and the problem of short storage time caused by easy aggregation after preparation in a traditional mode is avoided.

Description

technical field [0001] The invention relates to the technical field of protein nutrient solution, in particular to a nano-selenoprotein nutrient solution for animals and plants and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for humans, animals and plants. Selenium has important biological functions such as anti-oxidation, regulating immunity, and antagonizing harmful heavy metals. Selenium deficiency is associated with more than 40 diseases. Appropriate selenium supplementation can effectively prevent and control related diseases, thereby helping the growth and development of animals and plants, avoiding diseases in breeding, helping to increase production and reduce breeding production costs. [0003] The traditional preparation methods are divided into two categories, one is to use protein, polypeptide, dextran, melatonin, chitin and mixed amino acids as templates to obtain composite nano-selenium; the other is to u...

Problems solved by technology

[0003] The traditional preparation methods are divided into two categories, one is to use protein, polypeptide, dextran, melatonin, chitin and mixed amino acids as templates to obtain composite nano-selenium; the other is to use phycocyanin with antioxidant activity Direct reduction of selenium compounds to obtain composite nano-selenium; From the perspective of these preparation processes, they are obtained by reacting template protein molecules and reducing agents with selenium compounds at the same time, and the selenium nanocomposites produced are mainly surface adsorption of template molecules. Easy to aggregate, it is not convenient for long-term storage, convenient for animals and plants
